Hello, I have a CoreDuo 1.83 macbook, 1GB, 60GB Hdd, i was looking to buy more RAM and a bigger HDD for this holiday season. The RAM i will purchase from Crucial but the HDD i have been looking and i want to know what exactly i need. do i need ATA ? SATA ? (or even ATA-100 or SATA-150?) these are what is confusing me. I know it needs to be a 2.5" HDD but then i started seeing these extra little things and i dont want to buy the wrong one. I was hoping to get around a 120-160GB (or more if its cheap, <200$) Can anyone reccomend some HDD's or possible just the criteria a new one would need to meet to work in my macbook? (Side note: does anyone know the max size HDD my macbook would recognize? is it 320? or so ) Thanks all !
